In Bed With My Roommate's Fiancé by Eloise Winslow

She was supposed to be off-limits. Her fiancé was his best friend. But when Maya moves in temporarily, the electric tension between them becomes impossible to ignore - a spark that ignites the moment they're alone. Late nights in their shared space become a dangerous dance of lingering touches, heated glances, and whispered confessions. What starts as stolen kisses in hallways escalates into passionate encounters that leave them both breathless and desperate for more. She's torn between loyalty and desire. He's consumed by need he can't deny. Every time they promise it won't happen again, they find themselves tangled in sheets, his hands exploring every inch of her body while she arches into him, crying out his name. The guilt gnaws at them both, but the pull is too intense, too overwhelming to resist. Their bodies betray what their minds insist is wrong. As the wedding date approaches, the lies grow heavier, the secrets more dangerous. Can they continue hiding what's become the most real thing either of them has ever felt? Or will their scorching affair destroy everything - and everyone - around them? Some desires can't be denied. Some connections burn too hot to extinguish.
